'I fell asleep behind the wheel': 7 years in prison for man convicted of killing 2 bicyclists

MUSKEGO, Wis. -- (WITI) -- 22-year-old Brett Hartley of South Milwaukee, convicted in connection with a June 2015 crash that killed two bicyclists near Muskego was sentenced Thursday, June 22nd to serve a total of seven years in prison.

Hartley in April pleaded guilty to two counts of homicide by negligent operation of a vehicle.

He was sentenced to serve three-and-a-half years in prison and three years extended supervision on each charge. The sentences are to be served consecutively, so he'll serve a total of seven years in prison, and six years extended supervision.

A restitution hearing was set for September 19th.

The crash happened on June 6th, 2015. Prosecutors say Hartley hit and fatally injured two close friends and co-workers who were training for an Iron Man — 45-year-old Paul Brown of Franklin and 54-year-old Anthony Oliver of Oak Creek.

Muskego police released the 911 recordings — which included the voice of Hartley:

Dispatch: “OK. OK. Hold on a minute. Just hold on, OK?”

Caller: “They were biking and then ah… I, I fell asleep and I woke up and then I hit two people.”
